I never wonder about this, because we have.

  Have you considered taking a history class? Or, if you're not out of high school, paying attention in the ones you're required to go to. 

Do you have a link to back up your statement or are you just spewing out information you have no clue about?

When i say Light speed travel i mean humans actually being able to travel at that speed not particles , when i say discover a habitable planet i mean humans actually landing on the ground and living there. I think you get my point

It was a reply to the thread title, not any specific idea in the OP.
